TrieKV: Managing Values After KV Separation to Optimize Scan Performance in LSM-Tree
Persistent key-value(KV) stores are mainly designed based on the Log-Structured Merge-tree(LSM-tree) for high write performance, yet the LSM-tree suffers from the inherently high I/O amplification which influe...

HTStore: A High-Performance Mixed Index Based Key-Value Store for Update-Intensive Workloads
In this paper, we propose a high-performance Mixed Index based key-value store named HTStore to improve the write and read performance in update-intensive workloads of LSM-tree based key-value stores. The key ...
